This study examined what kind of play spaces mothers have given children, how those play spaces were related to their child-rearing anxiety, what kind of differences existed between a mother with many play spaces and a mother with few play spaces in terms of their anxiety, their networks for child-rearing, and their experience of "family of orientation". The result indicated that mothers with many play spaces tended to have less anxiety, more networks for child-rearing and richer experiences in their "family of orientation" than mothers with few play spaces. It was considered that the intergenerational transmission of child-rearing is reflected. It also suggested that the number of children's play spaces reflected transmission of knowledge of child-rearing influenced.
